Part III. Read the passage then choose the correct answer to each question. Circle A, B ,C or D

The play now on at the New Theater as part of the Eastern Arts Festival is not among the best plays
for which the director, Army Fielding, has been responsible.The action takes place in the home of
Professor Spear. One night his landlady comes to the house for a chat. After inviting her in, the professor
hears a sound and thinking it is a burglar coming to rob the house, fires his gun. By mistake the wrong
person is shot and the thief gets away. The scene of the second act is a law court, in which everyone waits
to find out if the professor is guilty of murder.
I did not care for the acting in some cases. Norman Jones is normally seen in some comedies and it is
not satisfactory as the professor. He doesn’t look like a wise old man. Also Simon Fry, as the servant,
shouted at the top of his voice through the play. The hit of the evening, however, was James Smith as the
judge. On the whole, the play appeared to be a little out of date. I can think of many other plays which
would have been more suitable for a group of clever young actors to perform. The play continues until the
end of the month.
1. The passage is from ________.
A. a review of the play. B. an instruction to a book.
C. a letter. D. an advertisement.
2. What is the writer trying to do ?
A. To give advice to the writer of the play. B. To warn people not to go and see the play.
C. To give his own opinion of the play. D. To persuade the director to change the
play.
3. The writer’s opinion about the play is that ______.
A. there were not enough actors for the parts.
B. the actors would have performed better in a modern play.
C. the play was being performed at the wrong time of the year.
D. the play was a comedy but the audience did not find it amusing.
